This is for an r26418 image generated locally for the Ubiquiti M900 series.
The signal strength forecast by Radio Mobile is -68 dBm. The path is
2 Km. Clearly, there is one tree in the Fresnel zone; if wrong about
the Fresnel zone, the worst case is 300 meters of trees without much
foliage this time of year.
Presuming this is a noise problem, is there a sw tool which will
provide us with the manufacturer|mac address of the device which may
be causing the noise?
The two measurements below were taken 5 to 10 minutes apart.
What possibilities exist other than noise for such a poor signal strength?
THANKS for your help.
kind regards/ldv
